a iull, clear, and exact description.

This invention relates to powder blowers' and more particularly to an attachment adapted to be appliedto a can or container of powder `whereby the powder can be forced out from the can .or container. by puffs.

The invention has for its general objects to provide a comparatively.simpleandE inexpensive powder blower in the 'nature of an attachment which is easily and 'quickly applied to a container and is adapted. to be.

used over and over a ain. A further object o. the invention is the provision 'of a powder discharging device which consists of a body having a bulb fastened thereto for forcing air into the powder container or can, whereby powder is discharged through the nozzle of the body, there being in the body a combined tube and bulb fastening device through which the air passes from the bulb to the can or container, and around this tube is provided an annular space through which the powder and air pass to the discharge nozzle.

With such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features' of construction and arrangement of parts which will be set vforth with particularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention, and wherein similar characters of reference indicate corresponding parts in all the views, Figure l is a side view of the powder blower shown applied to a powder container; Fig. 2 is a vertical section of thedevice shown in use; and Fig. 3 is a view of a combined bulb clamping device and air tube shown detached.

Referring to the drawing, A designates the powder blower and B a container or. can for the powder.` This can is provided with an opening l which may be threaded' or otherwise formed to receive a plug or other stopper which is removed so that the opening l can .receive the powder blower.

The powderblower comprises a body 2 madeof any suitable material and of tubular form, the lower end or the body being shown threaded at 3 to screw into the openin 1. The upper end of the body 'has a conica or other shaped seat d against which the bulb 5 is clamped.

Communicating' with the bore 6 of the body 2 is a laterally extending nozzle '1 through which the device.

Arranged withinthe body and extending longitudinally of the bore thereof is an air tube 8 which is of smaller diameter than the bore 6 so as to provide an annular passage up which the powder passes to the nozzle?. The upper portion ot this tube is formed into a head 9 which -is considerably lar than the opening l0 in the bulb. provi i accommodate such 'headu The under side il oi Ithe head 9' ooperates with the seat 4 to clamp the marginal portion 'l2 around the opening l0 to the body2 oi the device. The air tube 8 is fastened in the body 2 by means of screw threads 134 engaging the threads 1d inthe upper endoi the bore i3 so that by relative turning of the parts 2 and 8 the bulb can be clamped tightly between the body 2 and head 9 to form an airtight joint, and to facilitate this relativev turnlng of the parts the lower end of the air tube preferably extends out or the body 2 far enough to enable it to be ed by the thumb and iingers of one an while the other hand grasps the body 2.

In o eration the bulb .5, which is northe powder'is blown out of.

mally lled with air, is compressed as shown in Fig. 2, whereby the air is forced downwardly through the tube 8 and intov the container B. This air agitates the powder -in thecontainer so that the agitated powder isifentrained with the air as it escapes upwardly through the. annular passage 15 from which the' powder discharges to the nozzle 7. When the bulb expands, the discharge of powder ceases as au' is drawn inthrough the nozzle 7, passage 15, container B and air tube 8. f

From the foregoing description taken in connection with the accompanying drawing,

lthe advantages of the construction and method of operation will be readily understood by those skilled in the .art to which the invention appertains, and while have described tlie device which I now consider to be the best embodiment thereo, 1 desire to have itunderstood that the deviceshown is f merely illustrative, and that such changes v v claim as new and desire to secure by Letters Patent 1. A powder blower comprising a body having a bore extending therethrough and having a: seat at one end and attaching means at the opposite end, a bulb hating an opening, anair tube extending into the opening of the bulb and having a head disposed therein., means for fastening the tube and body together to clamp the bulb between the said seat and'head, a discharge nozzle connected with the said body, and a passage in the said body communicating with the nozzle and through which powder discharges when air is forced from the bulb throuh the said tube.

2. powder blower comprising a body having a bore extending therethrough, an

internal thread in the outer end of said bore, a seat on the outer end of the bore, an air tube extending through the bore of the body and longer than the latter, a thread adjainea-,eee

cent the outer end oi" the tube for screwing into the body, a head onV the outer end of the tube, a bulb having an opening to accommodate the head and clamped between the latter and said seat, said tube being of less 'diameter than the bore of the body to form an annular powder discharging passage, and a nozzle connected with the body and' communicating with the said passage.

3. A powder blower comprising a body having a bore, an ail-'tube screw threaded in the bore and having a portion of less diameter than the bore to form a powder` discharging passage, a nozzle on the body communicating with the said passage, a head on thetube, and air discharging means coinmunicating with the air tube and clamped by the head of the latter against the said body.

lin testimony whereof i have signed my name to this specification in the presence of two subscribing witnessesu aaneen siriana.
